List of American and Canadian soccer champions

Despite each receiving FIFA-affiliated status in 1913, both the United States and Canada have lacked a consistent, multi-division soccer system until recently. Consequently, the determination of champions has been problematic at times. The United States did not have a truly national top flight league until the FIFA-sanctioned United Soccer Association and the "outlaw" National Professional Soccer League, which had a network television contract, merged in November 1967 to form the North American Soccer League (NASL). The NASL considered the two pre-merge forerunner leagues as part of its history.

Before 1967, there were several regional and city leagues of various levels of quality. For example, the first and second incarnations of the American Soccer League constituted the premier level of professional soccer in the Northeastern United States, but they and teams from the St. Louis Soccer League would regularly defeat the best the other had to offer. These are only two of the most notable leagues of the regional era, as there were professional and amateur competitions in Chicago, California, the greater Western United States, Ontario, and Western Canada, among several other regions.

While the creation of the NASL in 1968 brought bonafide top-flight competition to the U.S. and Canada, its collapse in 1984 saw a temporary return to the fragmented regional structure. The merger of the Western Soccer League and third iteration of the American Soccer League created a national second division in the U.S. known as the American Professional Soccer League (APSL) in 1990. The APSL later absorbed the Canadian Soccer League, which at the time was an attempt at a wholly first division within Canada.

It was not until the establishment of Major League Soccer (MLS) in 1996 as part of FIFA's agreement to award the United States the 1994 World Cup that there was again a truly national, sanctioned first division in either country. Top Canadian teams resided at the second division until MLS expanded to Canada in 2007.

Given the tumultuous history of professional soccer in the United States and Canada, there is a broad history of champions of various kinds in both countries, both in leagues that comprised both nations and cups that were held in only one. This article takes into account all these competitions to compile an accurate listing of American and Canadian soccer champions with an eye towards maintaining continuity.

Background
For teams in the United States and Canada, there are three major domestic trophies.

The primary focus is the league championship, a postseason knockout tournament held between the best teams from the regular season. This is presently determined via the MLS Cup. American and Canadian sports leagues typically have such playoff systems. These have their roots in long travel distances common in U.S. and Canadian sports; to cut down on travel, leagues are typically aligned in geographic divisions and feature unbalanced schedules with teams playing more matches against opponents in the same division. Due to the unbalanced schedule typical in U.S. and Canadian leagues, not all teams face the same opponents, and some teams may not meet an even number of times during a regular season, if at all. This results in teams with identical records that have faced different opponents differing numbers of times, making team records alone an imperfect measure of league supremacy. The playoffs allow for head-to-head elimination-style competition between teams to counterbalance this.

Secondary is the recognition of the best regular season record (an accomplishment known as the league premiership in Australia and New Zealand, countries with similar league structure to the U.S. and Canada). The MLS team with the highest point total during the regular season is awarded the Supporters' Shield.

Thirdly, there are the two countries' respective domestic cup competitions: the Lamar Hunt U.S. Open Cup and the Canadian Championship. These tournaments are unique to soccer among professional sports in the U.S. and Canada, as no other major team sport conducts competition outside of regular league play.

Additionally, American and Canadian clubs participate in the CONCACAF Champions League, a continental club competition in which the United States is allocated four qualification spots and Canada one. For American clubs, the winners of the MLS Cup, Supporters' Shield, and U.S. Open Cup all qualify, along with the regular season conference champion that does not win the Shield. The lone Canadian berth is determined by the Canadian Championship. Finally, there is the world championship as determined by the FIFA Club World Cup, a berth to which is earned by winning the Champions League.

American and Canadian soccer clubs exist in a franchise system, rather than a promotion and relegation system. As a result, teams do not systematically move between levels each season. This is standard among American and Canadian major and minor sports leagues and is part of the franchise rights granted by the leagues. Recently, a trend has developed where a club from the lower divisions may be "promoted" via an expansion franchise awarded by Major League Soccer.

American competitions
At various times, Canadian clubs have competed in the top-tier of American soccer, either in place of or alongside a Canadian top-tier league. Currently, three Canadian clubs compete in Major League Soccer.

National Professional Soccer League (1967)

 * Oakland also won the NPSL Commissioner's Cup nine days after winning the NPSL Finals.

North American Soccer League (1968–1984)

 * – The 1969 season featured no playoffs; the league title was awarded to the team with the most points in the season.
 * # The New York Cosmos dropped "New York" from name for the 1977 and 1978 seasons, then returned to the full name in 1979 season.

Modern era

 * – Championship awarded to Paterson when Scullin were unable to field a team for the replay, due to injuries and players under baseball contracts beginning the baseball season
 * – Before the Spring 1931 season, Fall River F.C. moved to New York City and merged with New York Soccer Club to become the New York Yankees. However, they began the 1931 tournament under the name Fall River, and as such were required to play as Fall River for the remainder of it, and won the Cup. Before the Fall 1931 season, the Yankees moved again, this time back north to New Bedford, Massachusetts. They merged with Fall River F.C. to become the New Bedford Whalers, and again won the Cup in 1932. The USSF officially credits "Fall River F.C." with four championships in total, and "New Bedford Whalers" with one.
 * – St. Louis Soccer League team names were determined by the club's respective corporate sponsor. The team known as Hellrungs from 1929 to 1931 was also known as Stix, Baer and Fuller F.C. from 1931 to 1934, St. Louis Central Breweries F.C. from 1934 to 1935, and St. Louis Shamrocks from 1935 to 1938. As the change was only cosmetic and no relocations or mergers with clubs resulting in new rosters were made, the club's title history continues with the name changes.
 * – Aggregate drawn 2–2, Championship shared when details for a third game could not be agreed upon.
 * – Brooklyn Dodgers S.C. returned to their original name of Brooklyn Italians before the 1990s (the club states the change was in 1974, though later U.S. Open Cup tournaments have them registered under the Dodgers name).

Trebles
In 2017, Toronto FC completed a treble of Supporters' Shield, MLS Cup and Canadian Championship, the first treble of any kind achieved by either an American or Canadian club since the beginning of Major League Soccer in 1996.

Doubles
Listed here are the teams to achieve two major accomplishments in one season since 1968.

Overall totals
Defunct franchises: †.


 * – If the full histories of the domestic cups were included, the table would be some 150 teams long and include dozens of defunct, historical, and strictly amateur (North American Division 4 or 5) squads. As North American Soccer League teams did not compete for the domestic cups, and for the sake of practicality, only the modern eras of the two domestic cup trophies (since 1995 for the U.S. Open Cup and since the inception of the Canadian Championship in 2008) are included in this particular chart. For full domestic cup histories and totals, see below.
 * – The current incarnation of the franchise is a namesake phoenix club that owns the rights to the club's name and history.
 * – Team currently exists as a professional franchise in a Division II or Division III league, and as such are prevented from competing for two of the three domestic majors due to a lack of promotion and relegation.
 * – The current incarnation of the franchise rebranded but owns the rights to the club's name and history.
 * – Canadian soccer team.

Division 2 leagues
Before the 1976 season, the American Soccer League placed its first teams on the west coast, going national. For the first time, the United States and Canada had a national-level second-division league. For 2017 the USSF granted provisional D2 status for both the NASL and the USL.


 * – In 1989 the two largest U.S. leagues, the American Soccer League and the Western Soccer League, played a title game between their respective postseason champions as a precursor to the next season's merger.
